230 The Rocky Mountain Locust. 



prothorax which extends to a tapering point to or beyond 

 the tip of the abdomen ; by the front of the breast forming 

 a projection like a stock-cravat into which to receive the 

 lower part of the head, and by the short, rudimentary, 

 scale-like front wings. They fly with a buzzing noise like 

 a flesh-fly. Our most common species ( Tettix granulata, 

 Scudder, Fig. 42,) may be called the Granulated Grouse- 

 Locust. Like the other species, it is very variable in color 

 [Fig. 42.] and ornamentation, the prevailing hue being 

 dark-brown beneath and paler above. A well- 

 marked variety has a small, pale spot on the 

 rudimentary front wings, and a larger conspic- 

 uous one on top of the hind thighs. The species 

 of the genus Stenobothrus also hibernate partly 

 grown, and are mistaken for spretus.

 In the spring of 18 75 the meadows were reported as being 

 destroyed around Champaign and Jacksonville, Illinois, by 

 what was supposed to be the young of spretus / but speci- 

 mens of these supposed locusts, sent me by Chapin & Sim- 

 mons, of the Jacksonville Journal, proved to be little Jas- 

 soid leaf-hoppers allied to the common grape-leaf hoppers 

 — insects belonging to a different order (Hemiptera) from 

 that which includes the locusts (Orthoptera.) They were 

 indeed grass-hoppers, in the sense of hojDping about among 

 the grass, but they were not the so-called grasshoppers 

 (locusts) that at the time were proving such a plague in 

 parts of Kansas and Missouri. 



PROSPECTIVE INJURY. 



It is of course impossible to predicate with assurance 

 injury or non-injury from the fall swarms. There were no 

 locusts to do harm in Manitoba in 1876, and it would
